MILLING- AT'IACHMENT FOR METAL-WORKING MACHINES.

Patented Feb. lit, 1919.

Application filed November 16, 1917. Serial No. 202,308.

being employed as a matter of convenience but comprehending theapplicability of the device to metal working machines of various typesincluding lathes, milling machines, and similar apparatus,

Attachments for performing the functions of this invention now wellknown are all limited as to use to such an extent that they are suitablefor only certain kinds of work, and in applying them to lathes, forexample, especially of small size, so much room is occupied by themechanism of the attachment that there is little space for handlingwork. This has led me to devise the present apparatus of suchconstruction as to give it the greatest latitude of adjustment so thatit is what may be called a universal construction or one characterizedby the absence of the restrictions hitherto ob-- served in apparatus-forthe same purpose.

To this end the device is intended for attachment to the cross slide ofa lathe either directly or indirectly, by a special plate which isfurnished, and in combination with the longitudinal movement of thelathe carriage, the transverse movement of its cross slide, and its ownadjustment as hereinafter explained, practically all adjustments, horizontal, vertical and angular, may be obtained as desired.

In the accompanying drawmgs:

. V Figure 1 isan end elevation of the attachment as applied to a lathe,including the angle plate work table intended for mach ning sections ofrounds, squares, etc., whlch .do not" require indexing, said table beingtilted at an angle from the horizontal as desired when beveling the endof a section or bar" 7 Fig.2 is a vertical sectional view on the planeindicated by the line 22 of Fig. 1; .Fig. 3 is a top plan view;

Fig. 4 is a fragmentary view showing the indirect application of theattachment to the lathe as by means of an extension plate;

Fig. 5 is a perspective view of the extension plate alone;

Fig. 6 is a front elevation of a vise attachment for use with thisinvention;

Fig. 7 is a vertical sectional view on the line 77 of Fig. 6;

Fig. 8 is a side elevation of the attachment as applied to a benchmiller; and

Fig. 9 is a plan view of the device as shown in Fig. 8.

Referring to the drawings, Figs. 1, 2 and 3 show the construction of themilling attachment as arranged for plain milling, where indexing is notrequired, the same consisting of the angle frame or standard 1, thevertically adjustable slide 2, and the angle plate work table 3. At oneside the standard is provided with a flat base 4 and spacedstrengthening ribs 5, while on the other side, its front face, is aguide 6 on which the slide 2 is mounted, said slide being adjustableupwardly and downwardly by means of the handle screw 7. A circularflange 8 projects laterally from the slide and is provided with acircular slot 8 in which are received the T-headed bolts 9, in turnconnecting thereto the correspondingly formed flange 10 of the angleplate work table 3 above mentioned.

The flange 10 is formed with a circular tongue 10 fitting in the slot 8and it will be apparent that this construction permits of completelyrevolving the work table 3 about a horizontal axis so that work may beheld in a horizontal or vertical position, as well as at any angletherefrom. The angle plate work table 3 is slotted as indicated at 11 toreceive T-headed bolts 12 holding the clamp 13 for supporting the workon said table. A variety of work can he held on this angle plate worktable, as many means are at the disposal of mechanics for clampingvarious pieces to the table as is now done on milling machines. Thistable can be inverted and work may be clamped to its under side, whichwill then be the top, and this will present a larger surface for certainpieces of irregular shape. In such enabling the scope of adjustment inthe different planes which has hereinbefore been referred to and whichproduces a most practical apparatus for application to the various typesof metal working machines that may be required.

Having thus described my invention, what I claim as new is:

1. The combination with a lathe or similar machine and cross slidethereof, and means for producing movement of the slide, of an attachmenttherefor including a supporting standard, a Work holding support mountedon said standard at one side thereof so as to be free to move above andbelow the plane of the cross slide aforesaid, and a connection directlyconnecting the said standard to the cross slide and about which saidstandard is free to com pletely revolve when above said plane whereby tohold the work at any angle in a horizontal plane.

2. The combination, with a lathe or similar machine having a crossslide, of an attachment therefor including an upright work holdingsupport, the vertical face of which lies in substantially the same planeas the inner edge of the cross slide, said support having an offset basedisposed upon the cross slide, and a pivot connection connecting saidbase to the slide, said support being adjustable about said connectionto hold the work at any angle in the horizontal.

3. The combination, with a lathe or similar machine having ahorizontally and transversely movable supporting member, of anattachment therefor comprising an upright standard having its basesupported on said supporting member, a connecting member connecting saidstandard to the supporting member and permitting movement of the formercompletely about the connecting member, a slide mounted on saidstandard, means for adjusting said slide vertically to points below theplane of the lathe supporting member, and a work holding device havingswiveled connection with said slide, whereby to afford longitudinal andtransverse adjustments of the work and angular adjustments in bothhorizontal and vertical planes.

4-. The combination, with a lathe or similar machine having a crossslide, of an at tachment therefor comprising an upright standard havingan angle base offset at one side, a pivot bolt connecting the base ofsaid standard directly to the cross slide, a vertically movable slidemounted on said standard, and means for adjusting said slide, saidvertically movable slide having its face provided with an annularflange, and an angle plate work holding device swiveled to the slide andhaving one edge arranged at a greater distance from its center than theopposite edge, whereby to support the work nearer or farther away fromthe tool held by the lathe.

5. The combination with a lathe or similar machine having a cross slide,of an attachment therefor comprising a standard formed with a laterallyprojecting base, work holding means mounted upon said standard, anextension plate secured to the cross slide and adjustable about its connection with the cross slide, and a connection connecting the base ofthe standard to the extension plate and about which connection saidstandard is revoluble to adjust the work with respect to the slide andto anv' angle in the horizontal plane.

In testimony whereof I aifix my signature.
